To get the order of magnitude of the gravitation force between two bodies separated by some distance, the equation used is
F = G m₁m₂/d²
Using the given values from the problem
F = 6.67x10⁻¹¹ (1)(1) / (1)²
F = 6.67x10⁻¹¹
So, the answer of magnitude is
<span>OPTION (4) -11</span>

Ganezh [65]

Answer:

Government & Public Administration

Jobs in the government and public administration career cluster involve planning, managing, and providing government legislative and administrative and regulatory services and related general purpose government services at the federal, state, and local levels.

This career cluster is divided into seven pathways:

Governance

National Security

Foreign Service

Planning

Revenue and Taxation

Regulation

Public Management and Administration

Governance

Officials involved in the governance pathway uphold the structure of our government. They typically work with constituents, or voters represented by elected officials; while others resolve conflicts among interest groups with opposing goals.

Sample occupations include:

Legislative Assistant

Congressional Aide

Lobbyist

County Commissioner

Senator

Representative

Mayor

Governor

Lieutenant Governor

National Security

Maintaining a strong national security encompasses such diverse activities as running a hospital, commanding a tank, programming computers, operating a nuclear reactor, or repairing and maintaining a helicopter. The military provides training and work experience in these fields and many others for more than 2.5 million people who serve in the active Army, Navy, Marine Corps, Air Force, and Coast Guard, their Reserve components, and the Air and Army National Guard.

Sample occupations include:

Combat Control Officer

Missiles and Space Systems Officer

Submarine Officer

Munitions Officer and Specialist

Infantry Officer and Specialist

Air Defense Artillery Officer

Military Intelligence Officer

Cryptographer

Intelligence Analyst

Foreign Service

People working in the Foreign Service pathway help to ensure peaceful relations between the U.S. and foreign countries. They also aid immigrants wanting to live and/or work in the U.S. These people serve mainly in embassies, consulates, diplomatic missions, and in Washington, D.C.

Sample occupations include:

Foreign Service Officer

Diplomatic Officer

Consular Officer

Ambassador

Diplomatic Courier

Planning

People who work in the Planning pathway develop long- and short-term land use plans to provide for growth and revitalization of urban, suburban, and rural communities, while helping local officials make decisions concerning social, economic, and environmental issues.

Sample occupations include:

Planner

Census Enumerator

Census Clerk

Federal Aid Coordinator

Economic Development Coordinator

Chief of Vital Statistics

Revenue and Taxation

People who work in the Revenue and Taxation pathway ensure that governments obtain revenue from businesses and citizens by collecting audits, monitoring taxes payable and collecting overdue tax dollars.

Sample occupations include:

Tax Examiner

Tax Clerk

Revenue Agent

Internal Revenue Investigator

Assessor

Auditor

Regulation

People who work in the Regulation pathway will typically possess a body of technical knowledge about an industry, the environment, or technology. This –coupled with a knowledge of related laws, rules, and regulatory systems –permit regulators to protect our health, safety, and environment as well as ensure the integrity of our financial, transportation, and public utility industries.

Sample occupations include:

Investigator/ Examiner

Code Inspector

Bank Examiner

Election Supervisor

Child Support Officer

Cargo Inspector

Border Inspector

Aviation Safety Officer

Public Management and Administration

Government agencies and public corporations and trusts have specific and rigorous standards for the stewardship of public resources. Public management careers will require technical skills related to budgeting, personnel management, procurement or other activities, and specific knowledge of the regulations and other policies that govern public management.

Sample occupations include:

Court Administrator or Clerk

City or County Clerk

City Council Member

City Manager

Purchasing Manager

Four blocks of weights are required using which any body whose weight is between 1kg and 40 kg can be weighed. Find the four wei
Vikentia [17]

Answer:

The weights are 1 kg, 3kg, 9kg and 27kg.

Explanation:

The weights are 1 kg, 3kg, 9kg and 27kg.

1+3+9+27= 40

27+9+3= 39

27+9+3-1=38

27+9+1=37

27+9=36

27+9-1=35

27+9+1-3=34

27+9-3=33

27+9-3-1=32

27+3+1=31

27+3=30

27+3-1=29

27+1=28

27

27-1=26

27+1-3=25

27-3=24

27-3-1=23

27+3+1-9=22

27+3-9=21

27+3-9-1=20

Like this all the weights from 1 to 40 kg can be made using 1,3,9 and 27 kg.

A 1.60 m cylindrical rod of diameter 0.550 cm is connected to a power supply that maintains a constant potential difference of 1
bija089 [108]

1.

Answer:

Part a)

\rho = 1.35 \times 10^{-5}

Part b)

\alpha = 1.12 \times 10^{-3}

Explanation:

Part a)

Length of the rod is 1.60 m

diameter = 0.550 cm

now if the current in the ammeter is given as

i = 18.7 A

V = 17.0 volts

now we will have

V = I R

17.0 = 18.7 R

R = 0.91 ohm

now we know that

R = \rho \frac{L}{A}

0.91 = \rho \frac{1.60}{\pi(0.275\times 10^{-2})^2}

\rho = 1.35 \times 10^{-5}

Part b)

Now at higher temperature we have

V = I R

17.0 = 17.3 R

R = 0.98 ohm

now we know that

R = \rho \frac{L}{A}

0.98 = \rho' \frac{1.60}{\pi(0.275\times 10^{-2})^2}

\rho' = 1.46 \times 10^{-5}

so we will have

\rho' = \rho(1 + \alpha \Delta T)

1.46 \times 10^{-5} = 1.35 \times 10^{-5}(1 + \alpha (92 - 20))

\alpha = 1.12 \times 10^{-3}

2.

Answer:

Part a)

i = 1.55 A

Part b)

v_d = 1.4 \times 10^{-4} m/s

Explanation:

Part a)

As we know that current density is defined as

j = \frac{i}{A}

now we have

i = jA

Now we have

j = 1.90 \times 10^6 A/m^2

A = \pi(\frac{1.02 \times 10^{-3}}{2})^2

so we will have

i = 1.55 A

Part b)

now we have

j = nev_d

so we have

n = 8.5 \times 10^{28}

e = 1.6 \times 10^{-19} C

so we have

1.90 \times 10^6 = (8.5 \times 10^{28})(1.6 \times 10^{-19})v_d

v_d = 1.4 \times 10^{-4} m/s
